Question
A 10-month-old girl baby often wakes up at night, sometimes even up to 8 or 9 times a night, often accompanied by sweating and crying. This situation has been going on for over two months, and if she is not held, her crying becomes more intense. She had previously been supplemented with calcium and cod liver oil, and her trace elements test showed no deficiency. But calcium and cod liver oil have not been used for about two months. I would like to ask what may have caused this, and whether it is related to brain development.
Answer
Based on your description, it is speculated that the nighttime sleep restlessness may be due to insufficient calcium intake. A deficiency in calcium in infants can increase neural excitability, leading to nighttime waking and restless sleep. It currently seems unlikely that this is due to brain development issues, as infants at this stage have a fast rate of growth and development, requiring a higher calcium intake. I suggest resuming supplementation of calcium and vitamin D3 for your baby, and trying to expose your baby to sunlight outdoors to help with calcium absorption.
